What is a wetland and why is it important?

Wetlands must have one or more of the following three attributes: 1) at least periodically, the land supports predominantly hydrophytes; 2) the substrate is predominantly undrained hydric soil; and 3) the substrate is saturated with water or covered by shallow water at some time during the growing season of each year.

Can wetlands be filled in?

New Permits Expand Wetlands Regulation-Half Acre or Less Now Regulated. Most of these NWPs can only be used to fill 1/2 an acre or less of wetlands. An important consequence of these changes is to make property with as little as 1/10 an acre of wetlands subject to regulation under federal and state law.

What are some examples of wetlands?

The main wetland types are swamp, marsh, bog, and fen; sub-types include mangrove forest, carr, pocosin, floodplains, mire, vernal pool, sink, and many others. Many peatlands are wetlands. Wetlands can be tidal (inundated by tides) or non-tidal.

Can wetlands dry up?

Water levels vary seasonally (usually becoming drier in the late summer and fall, and having more water in the spring or after heavy rainfalls), even those that get their hydrology from groundwater. When we have extended dry cycles or drought, even open-water wetlands can go completely dry.

How can you identify a wetland?

Wetlands are delineated by observing the presence or absence of three variables: hydrology, dominant plant species, and hydric soils (USACE, 1987). All three indicators must be present during the growing season for a waterbody to be considered a wetland.

Where are most wetlands located?

Swamps and marshes are generally found in warm climates. Bogs are more common in cold or even Arctic areas in North America, Europe, and Asia. They also exist at high altitudes in warmer regions, such as the Sierra Nevada in the United States. Bogs are often called moors or fens in Europe, and muskegs in Canada.

What are benefits of wetlands?

Wetlands provide many societal benefits: food and habitat for fish and wildlife, including threatened and endangered species; water quality improvement; flood storage; shoreline erosion control; economically beneficial natural products for human use; and opportunities for recreation, education, and research (Figure 28)

What are wetlands good for?

Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. Wetlands can be thought of as “biological supermarkets.” They provide great volumes of food that attract many animal species. These animals use wetlands for part of or all of their life-cycle.

Perhaps the best way to protect wetlands is to educate the public of their benefits. If the public does not recognize the benefits of wetland preservation, wetlands will not be preserved.

Do wetlands filter water?

Wetlands are some of the most endangered ecosystems on the planet. When wetlands are drained, their environmental benefits such as filtering water are lost as well. Wetlands act as natural filters, removing sediment and toxins from the water.

How deep is a wetland?

Restored wetlands range in depth from surface saturated soils up to about 6 feet of standing water with an desired average depth of 18 inches. Water control structures are used to manage wetlands by raising and lowering water levels.
